Hi,
I am an MIT grad student currently working on a research project in the lab. The project requires me to send very high sinusoidal current into a low resistance load at high frequencies. In terms of numbers, we would like to send 0.1V across 0.001-0.01Ohms, which means we need 10A-100A, all of that at 1-50MHz. Since our waveform generator have low power and 50Ohms output impedance, we can't use them directly to drive that.
I've been thinking of using high-current op amps like the OPA549 as unity gain buffers to help me achieve that. Would you recommend that method? If not, what devices and methods would you recommend to help me send that signal?
THanks,
Ruben
